[Cython] PEP 380 approved: syntax for generator delegation

[Stefan Behnel]

Hi,

PEP 380 ("yield from") recently went through the approval gate.

http://www.python.org/dev/peps/pep-0380/

The implementation in CPython isn't rounded up yet and lots of tests are 
missing from the test suite. But it's agreed that it'll make it into 3.3, 
and we should try to support it as well. It's a really nice feature.
